Title: Improvements in or relating to mechanical loaders for loose materials
IPC: B65G21/14
Filed: 1942-02-21
Abstract: 555,454. Mechanical loaders. SUTCLIFFE, Ltd., R., and SHEPPARD, J. Feb. 21, 1942, No. 2322. [Classes 78 (i) and 78 (iv)] In mechanical loaders, for loose materials, comprising a main conveyer extending parallel with a long-wall coal, &c. face from gathering mechanism at the head, and an auxiliary conveyer normally operating at right angles to the coal face and extending between roof props, &c. to deliver the coal to removal means, the auxiliary conveyer is pivoted to the body of the machine so that as the loader advances and the auxiliary conveyer comes up against a prop the auxiliary conveyer is gradually turned rearward by the pressure thereon of the prop. The auxiliary conveyer 1 is mounted on a turntable 4 which forms a reduction gear box for the drive between the main driving shaft 2 and the conveyer chains through sprockets 12. The sprockets 12 are located intermediate between the end sprockets 11 of the conveyer so that the conveyer is capable of making its usual telescoping traverse to edge round props, &c. The conveyer has in addition a tilting motion about a horizontal axis to allow of height adjustment of its delivery end, a lifting jack 7 operated by a handle 8 being provided. The auxiliary conveyer can turn through about 200 degrees, but rotation beyond these limits throws the traversing mechanism of the loader out of gear.

Title: Improvements in Weighing Apparatus.
IPC: G01G1/26
Filed: 1916-02-17
Abstract: 103,707. Avery, W. & T., and Parnall, T. St. J. B. Feb. 17, 1916. Sliding-weight apparatus.-Relates to the kind of weighing-apparatus described in Specifications 4935/05, 13544/06, and 15690/09, and consists (1) in removing the main driving-shaft and its friction driving-clutch from the free end of the steelyard to the fulcrum end, so as to permit of a positive toothed gear connexion with the poiseweight propelling mechanism, (2) in employing a one-way clutch which serves the purpose of permitting the rachet-wheel and totalizing load-counter previously used to remain stationary during the return traverse of the poise weight, and at the same time allows the counter to be located at the free end of the steelyard in positive gear connexion with the ratchet-wheel, and (3) in providmg means of adjustment whereby the poise weight may be accurately located at the zero position upon the completion of its return traverse. As shown in Fig. 2, the main driving-shaft 4 is located near the fulcrum 1<a> of the steelyard 1, and the poise weight 2 is traversed in the outward direction by means of the friction clutch 3a, 3b, spur-wheels 6, 7, 9, bevel-pinions 22, 23, and screw 24. The part 3<b> of the clutch is integral with the spur-wheel 6 and is loose on the shaft 4, the driving-part 3a of the clutch being pressed against the loose part by a spring 5. At the position of equilibrium, a ratchet-wheel 11 is locked as described in Specification 15690/09, and this action, operating through a sprocket-wheel 13 and chain 17, arrests the gear-wheels 6, 7, 9 and the poise weight. During the forward movement of the poise weight, the ratchet-wheel 11 drives the counter 14 directly through gear-wheels 15, 16. After removal of the load, the fall of the steelyard rotates a rod 26 and couples up a clutch 28, 28<a>, and the return movement of the poise weight is effected by means of a driving-chain 29 connecting the shafts 4, 8, the counter being unaffected owing to the presence of a one-way clutch in the sprocket-wheel 13. In order to locate the poise weight accurately at the zero position, a cranked arm 18, which operates the clutch 28, 28<a>, is provided with an adjustable screw 19 adapted to be engaged by the poise weight at the zero position.

Title: Improvements relating to acrylonitrile
Filed: 1952-01-30
Abstract: In a process for the production of acrylonitrile by reacting acetylene and hydrocyanic acid in an acid reacting aqueous catalyst solution which contains ammonium and cuprous chlorides in a predetermined initial ratio, whereby ammonium chloride is constantly formed so lowering the rate of production of acrylonitrile, a portion of the catalyst solution is periodically withdrawn, cuprous chloride or its equivalent added to the catalyst solution, the amount of copper in the solution withdrawn and the copper added being substantially the same, so that the ratio of total ammonium chloride to total cuprous chloride in the catalyst solution is maintained substantially at the initial ratio.  The volume of catalyst solution is maintained substantially constant.  The copper compound may be added as a solid or in suspension or solution many such compounds being specified for addition representative being cupric chloride, cupric acetate, cuprous cyanide and cuprous oxide.  When other than a copper chloride is added, acidity should be maintained with hydrochloric acid.  A graph and tables are provided to show the diminishing rate of production of acrylonitrile with increasing motor ratios of ammonium chloride to cuprous chloride and to show that low ratios are preferable for a given concentration of cuprous chloride. pH should be maintained at 6.0 or lower.  In an example acetylene and hydrocyanic acid are reacted at approximately 90 DEG C. in the presence of cuprous and ammonium chlorides at pH about 1.0 maintained with hydrochloric acid, catalyst solution being periodically removed and copper added as an aqueous solution of cupric chloride to the original solution.

Title: Improvements in and relating to sound recording
IPC: G11B7/00
Filed: 1934-01-26
Abstract: 421,020. Optical sound - recording apparatus. KOLB, O. K., 39, Beverley Court, Wellesley Road, Chiswick, London. Jan. 26, 1934, No. 2759. [Class 40 (ii)] Relates to the making of photographic sound records comprising several parallel tracks of the variable width type, the widths depending both on the wave form and on the volume of the recorded sound. According to the invention, means are used whereby when changing from the smallest amplitudes or periods of silence to slightly greater amplitudes, the number of tracks on which recording is being effected increases. An example of recording apparatus for carrying out the invention is shown in Figs. 1 and 3. Light passing through a mask 2 is reflected by a vibratory mirror 3 (which is controlled both by the sound currents and by a rectified component thereof) on to a slit 4, through which it passes to the photographic film 5. The aperture 1 of the mask is shown in Fig. 3, which also represents a portion of the multiple track sound record produced. The aperture comprises two similar triangular portions on either side of a central portion 41 which is shaped as shown, and is of slightly greater height than the triangles. During silent intervals, or the recording of very small amplitudes, the slit is crossed only by the tip of the image of the central portion 4<1> of the mask, producing an effect at 3<1> only on the central track on the film. At greater amplitudes, recording occurs on all the five tracks simultaneously. A modified form of mask is described (Fig. 4; not shown), which is designed to effect transition from one to five tracks in successive steps. The mask used is preferably such that there is a linear relation between the movement of the light beam and the illuminated area of the sound record ; it may, however, be otherwise designed, for example, to give a " square law " response. The mask is preferably made on a photographic film by reproducing from an enlarged picture of the mask. The film emulsion used should be grainless or practically so ; the film known under the Registered Trade Mark " Printon " may be useful for this purpose.
